Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As Figure 1-5, a kind of crankcase ventilation system Oil-gas Separation separator assembly, it comprises the upper shell 1 of deaerator and the lower shell body 2 of deaerator, the upper shell 1 of described deaerator is harmonious with the lower shell body 2 of described deaerator, and perflation ventilation mouth 200 is had on the lower shell body 2 of described deaerator, the lower shell body 2 of described deaerator is provided with first turnover panel 201, second turnover panel 100 is provided with in the upper shell 1 of described deaerator, the lower shell body 2 of described deaerator is provided with first and gives vent to anger ventilated port 202, the upper shell 1 of described deaerator is provided with second to give vent to anger ventilated port 101, the lower shell body 2 of described deaerator is provided with return tube 203, maze board 3 is also provided with between the upper shell 1 of described deaerator and the lower shell body 2 of deaerator, it is characterized in that: between the upper shell 1 of described deaerator and the lower shell body 2 of deaerator, be also provided with smart separating plate 4, described smart separating plate 4 is provided with tornadotron 5, tornadotron outlet is had in one end of described tornadotron 5, and be provided with metal clips 6 in this tornadotron outlet port, tornadotron entrance 50 is had at the other end of tornadotron 5, described return tube 203 end is provided with scavenger valve 7, and oil return limited post 8 is provided with on described scavenger valve 7, the end of described oil return limited post 8 is provided with scavenger valve cover plate 9, the lower shell body 2 of described deaerator is also provided with metering hole 204.
Further, described tornadotron 5 quantity is 11 groups, wherein has four groups of tornadotrons to be normally open, and other seven groups is normal closed state.
Further, described metal clips 6 is arranged in the outlet port of wherein seven groups of tornadotrons 5.Carry out these seven groups of tornadotrons closed by metal clips 6, metal clips 6 herein can carry out design size as requested and often open the quantity of tornadotron, ensures the pressure loss that deaerator is less and high separation effect.
Further, the diameter of section at described metering hole about 204 two ends is greater than diameter of section in the middle part of metering hole.
Before pressurized machine is opened: mixed oil and gas by perflation ventilation mouth 200 successively after maze board 3, first turnover panel 201, second turnover panel 100, smart separating plate 4, metal clips 6 are separated, after being separated clean gas as shown in Figure 2 the first ventilated port 202 of giving vent to anger enter manifold;
